Rush Springs WWT - Secondary Wastewater Treatment Plant in Rush Springs, Oklahoma

Rush Springs WWT is a municipal wastewater treatment facility located in Rush Springs, Grady County, Oklahoma. The plant serves a population of approximately 1,278 residents, classifying it as a small-scale facility under U.S. EPA guidelines. The plant provides secondary treatment, which is the standard level required by the Clean Water Act for most municipal facilities. With a designed capacity of 567.81 thousand cubic meters per year and an actual discharge volume of 492.10 thousand cubic meters, the plant operates below its design capacity. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Oklahoma Department of Environmental Quality, ensuring compliance with federal water quality standards. The treated effluent is discharged into a local waterway that ultimately drains into the Washita River basin, a tributary of the Red River. This watershed supports agricultural activities and provides habitat for diverse aquatic species. The plant's secondary treatment helps protect downstream water quality in this ecologically sensitive region.

The plant discharges into a tributary of the Washita River, which flows into the Red River and eventually reaches the Gulf of Mexico. The Washita River basin supports a mix of agricultural and natural habitats, including wetlands that provide flood control and wildlife habitat. The secondary treatment process reduces organic pollutants and suspended solids, helping to maintain the ecological health of the downstream water bodies.
